This is an optional ST Racing Concepts CNC Machined Aluminum Precision
VLA 0° Rear Hub Carrier Set, and is intended for use with the Losi
XXX-SCT. CNC Machined from high-grade aluminum, these rear hub carriers
feature 0° of rear toe-in, and add great looks and durability to the
rear suspension of your XXX-SCT. New manufacturing procedures allow ST
Racing to hold tight tolerances at the bearing hole by drilling the
bearing holes after anodizing, which keeps the exact tolerance for the
bearing without being effected by the anodizing process. The hinge-pin
holes utilize set-screws underneath to secure the hinge-pins, helping to
prevent wear to the hinge pin holes in the hub carriers. This also
holds the hinge-pins in place in case the e-clips pops off the hinge-pin.

NOTE: Left and Right is determined in traditional way of looking from rear of the truck forward (opposite of kit plastic parts).
